Shakespeare ART-1 SWR/POWER METER.

This meter has a power range of 0 to 30.

This has been tested and it works. As far as frequency I'm not sure but I did test it on a Stryker radio and it did match my diawa CN-901 HP3 Type on the CB Band.

Due to part swappers and scammers there is no returns for this item. If you have any questions please don't hesitate to ask. I do get back to questions as you can see in my feedback. Thanks for looking. USA LOWER 48 Sates only. No Puerto Rico, Hawaii.
